Where be the Machines?
When building a science fiction world mechanizaton of some sort is very frequently going to come into play. Even in post appocoliptic, espically in post appocoliptic, settings the voice of an artificial lifeform can be a major plot point, a clue to the nature of the world, or a minor MacGuffin. So when builing a world remember that that annoying robo call from an insurance company has a place as well.
